A Case of Prosthesis Using Bone Graft and Dental Implants for Mandibular Defect Following Tumor Extirpation

Patient: A 15-year-old female complained of swelling and pain from the mental region to the left side of the mandible. The pathological diagnosis was ameloblastoma. The tumor, anterior teeth, and left canine on the lower jaw were extirpated. Since the missing part of the mandible was large, autogenous bone from the ilium was grafted therein. Following this, implants were inserted and implant-supported fixed prostheses placed theron. Discussion: Bone graft for the missing part of the mandible and dental implants improved the patient's QOL both esthetically and functionally. Inflammation of the soft tissue and resorption of bone around the implants were scarcely observed and the prostheses showed no complications. Conclusion: Autogenous bone grafts and dental implants for missing parts of the mandible after extirpation of ameloblastoma can provide esthetic and functional improvement, and are useful to obtain a satisfactory prognosis.
